Indonesia Adjusts Export Reference Price for Mining Products in April 2026

RRI.CO.ID, Jakarta - The Indonesian government adjusted the export reference price for mining products in early April 2026, reflecting global market corrections for major mineral commodities.

The Ministry of Trade set the Export Reference Price (ERP) for copper concentrate (Cu ≥15 percent) at USD 6,497.50 per Wet Metric Ton (WMT), down 4.35 percent from USD 6,792.97 per WMT in the second period of March.

Gold prices also weakened, falling from USD 165,118.45 per kilogram to USD 157,267.62 per kilogram. The Reference Price (RP) for gold was adjusted from USD 5,135.76 per troy ounce to USD 4,891.57 per troy ounce.

These provisions are outlined in Ministry of Trade Decision No. 559/2026 on Export Reference Prices and Reference Prices for Mining Products Subject to Export Duties. The regulation applies from April 1 to 14.

Director General of Foreign Trade at the Ministry of Trade, Tommy Andana, said the decline was influenced by changes in international mineral prices. “These mineral prices serve as a reference in calculating the ERP for copper concentrate for the first period of April 2026,” he stated in Jakarta on Tuesday, March 31, 2026, as quoted on the ministry’s official website.

During the data collection period, copper prices fell 3.53 percent, gold dropped 4.75 percent, and silver declined 7.68 percent. “The decrease in ERP and RP for gold resulted from a market correction following an upward trend in the previous period, along with adjustments in global financial markets,” Tommy explained.

The ERP and RP settings are based on technical recommendations from the Ministry of Energy and Mineral Resources, referencing international benchmarks. Copper prices refer to the London Metal Exchange (LME), while gold and silver prices are based on the London Bullion Market Association (LBMA).

“The determination of ERP and RP is carried out through inter-ministerial coordination involving the Coordinating Ministry for Economic Affairs, the Ministry of Trade, the Ministry of Energy and Mineral Resources, the Ministry of Finance, and the Ministry of Industry,” Tommy added. ***
